This invention is. an improvement in receptacles, particularly boxes or cartons made of cardboard or other sheet material and adapted to be flattened or collapsed for storage or shipment, and readily set up when needed for use.

An important object is to provide a box or carton to be given its final shape when it reaches the distributor who fills it with merchandise for the ultimate consumer; and having end walls connected to a bottom wall, all of which are constructed to facilitate the collapsing and subsequent formation of the box in the manner required.

A further object is to provide a box or carton of the kind mentioned that has a bottom wall comprising two longitudinal sections, side. Walls and end walls joined to each side wall, and connector segments between the end Walls and the sections of the bottom which move with each of the other parts into the positions for flattening the box or giving it the desired; final shape when allits parts and sections are distended for that purpose.

The drawings show a preferred embodiment of the invention, but. variations in. structural details may be adapted without deviation from the general plan of the improvement.

On said drawings:

Figure 1 shows a. blank so shaped that it can produce the box of this invention.

Figure 2 is a cross section showing one end from the inside of the box partly setup, the section being along the line 2-2' on Figure 4.

Figure 3 is a view similar to Figure 2, showing the parts in fully set up position.

Figure 4 is a side view partly broken away showing the box in collapsed position.

Figure 5 is a top view of what appears in Figure 4, and

Figure 6 is a bottom plan of the box partly collapsed, and at the begiiming of the setting up process.

The blank shown in Figure 1 comprises the side walls or sections l and 2 united by a bottom wall 3 which has a longitudinal score line 4 along the middle thereof. The side I has extensions 5 at both extremities connected to the section I by transverse score lines 6; and the section 2 has similar extensions I connected to it by transverse score lines 8; the score lines 6 and 8 being in line with each other and with the ends of the bottom section 3. The sections I and 2 are united to the two sections of the bottom 3 along the score lines 9 parallel to the middle score line 4. Also the extensions 5 have glue flaps l5. hinged to the ends 5 along score lines, similar to score lines 8. The sections or extensions 5 and 1- have. lateral projections H which are hinged thereto along extensions of the lines 9, and are L-shaped with square recesses in one edge adjacent the ends. of the bottom 3. These projections extend towards each other at,both ends of the box and terminate in edges I2 which are in line with the score line 4 of the bottom 3, and the recesses l3 are such as to make transverse oblong openings l4 when the blank is flat and distended. The corners l3 of these recesses are connected by diagonal score lines I5 to the intersections of the score lines 5 and 9, and 8 and 9 respectively, and'the score lines [5 mark off folding flaps I6 adjacent the ends of the sections of the bottom 3-, and united to parts of the edges of the ends: of said sections along extensions of the score lines 6. The remainders ll, of these projections H are hinged to the end wall sections 5- and 1.

To give this box its form, the sections l and 2' are bent up around the score lines 9 and-the sections 5 and l are bent crosswise of the ends of the bottom 3; so that the glue flaps I0 united to the sections 5 along score lines l8 can'be joined to the outer faces of the portions or sections 1. For this, the projections H are first bent in so that the major portions I! lie against the sections 5 and I; being folded around the diagonal score lines l5. The flaps 16 then extend upward from the ends of the sections of the bottom 3' at both sides of the line 4, and the portions- I! of the projections II are then disposed upon the inner faces of the extensions 5and las indicated in Figure 2. The box can then be flattened by bending the bottom upward and inward along the line 4 and the ends consisting of the sections 5 and l by folding along the lines I8 which run along the inner ends of the flaps 10. In this operation the projections II ar so moved that the halves of the bottom 3, and the flaps l6 and the entire remainders l! of the projections ll come into the same plane, with the entire projections ll making contact with the inner faces of the end wall sections 5 and 1.

The box can be stored or shipped in this collapsed state, but one can easily set it up by moving the end Walls consisting of the sections 5 and 1 towards the ends of the bottom, and pressing the two upturned halves of the bottom downward as shown in Figures 2 and 3. The main parts ll of the projections H are now held against the end sections 5 and 1 as before; and the triangular flaps l6 are folded downward 3 again upon the portions I! of the projections H. The box can then be filled with the two halves of the bottom flat and the end sections 5 and l in full transverse position across the ends of the box.

Having described my invention, what I believe to be new is:

l. A receptacle having a bottom and sides hinged thereto, the bottom being divided by a longitudinal score line into sections foldable together between said sides, ends hinged to the extremities of the sides, and foldable connector segments hinged to said ends, each segment being also hinged to part only of the edge at the adjacent end of one of said sections of the bottom.

2. A receptacle having a bottom and sides hinged thereto, the bottom being divided by a longitudinal score line into sections foldable together between said sides, ends hinged to the extremities of the sides, and foldable connector segments hinged to said ends, each segment being also hinged to part only of the edge at the adjacent end of one of said sections of the bottom, said segments being L-shaped.

3. A receptacle having a bottom and sides hinged thereto, thev bottom being divided by a longitudinal score line into sections foldable together between said sides, sections hinged to each extremity of said other sides and joined to make the ends of the receptacle, and fold.- able connector segments each hinged to part only of the edge at the end of one of said sections of the bottom and to each of said other sections.

4. A receptacle having a bottom and sides hinged thereto, the bottom being divided by a longitudinal score line into sections foldable together between said sides, sections hinged to each extremity of said other sides and joined to make the ends of the receptacle, and foldable connector segments each hinged to part only of the edge at the end of one of said sections of the bottom and to each of said other sections, said segments being L-shaped and extending towards each other.

5. A receptacle having a bottom and sides hinged thereto, said bottom being divided by a longitudinal score line into sections foldable together between said sides, a section hinged to each extremity of the sides, and foldable conector segments hinged to said sections, each segment being also hinged to part only of the edge at the adjacent end of one of said sections of the bottom, said segments having diagonal score lines upon the surface thereof.

the adjacent ends of the bottom and having diagonal score lines extending across their surfaces towards the junctions of the bottom and sides.

'7. A receptacle having a bottom and sides hinged thereto, the bottom having a score line dividing it longitudinally into two sections, other sections hinged to each extremity of the sides,

L-shaped connector segments hinged to each last named section and the adjacent section of the bottom along a part only of the edge at the end of said adjacent section, said segments extending towards each other, presenting recesses extending along the adjacent ends of the bottom, and having diagonal score lines extending across their surfaces towards the junctions of the sides and the bottom to, enable said segments to be folded when the box is set up or collapsed.

8. A receptacle having a bottom and sides hinged thereto, the bottom having a score line dividing it longitudinally into two sections, other sections hinged to each extremity of the sides, 7

L-shaped connector segments hinged to each last-named section and the adjacent half of the bottom, along a part only of the edge at the end of said adjacent section, said segments extending towards each other, presenting recesses extending along the adjacent ends of the bottom, and having diagonal score lines extending across their surfaces towards the junctions of the sides and the bottom to enable said segments to be-folded when the box is set up or collapsed, the last named score lines defining triangular flaps in said segments.
